Ozone Detection | Detectors Available at AirMet Scientific

Groundlevel ozone is an air pollutant with harmful effects on the respiratory systems of animals. The ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth''s surface. O 3 is also present in low concentrations throughout the Earth''s atmosphere and has many industrial and consumer applications. Ozone has a distinct sharp odour somewhat ...

Determining the Right Level of Ozone

Ozone Levels. The right level of ozone is when all the generated ozone is being consumed. This only applies to continuous ozone use in occupied environments not for shock treating. However, this is difficult to attain because it becomes a balancing act. Initially, the machine''s output is set high to get rid of the problem odor as quickly as possible. As this is being accomplished, less ozone ...
